This invention relates to a new and useful improvement in hinges of the kind known as piano hinges, and consists of the matters hereinafter described and more particularly pointed out in the appended claims.

In the case of hinges of the piano hinge type, in which the leaves extend the full length of the parts which are hinged together, it is necessary for the jobber or dealer to keep in stock hinges of many different lengths to meet the varied requirements of the trade. Some lengths are seldom called for, but at the same time, must be kept on hand to meet the infrequent demand.

The object of the present invention is to produce a hinge of the kind, comprising a plurality of unit hinge parts of uniform length, as a foot or half foot, or the like, designed for ready and easy assembly and connection of the required number of units to produce a hinge of the desired length. Thus, the jobber or dealer is only required to keep in stock, unit hinge parts to supply hinges of any length to meet the demands of the trade.

The advantages of the invention will appear more fully as I proceed with a description of the improved hinge in detail.

In the drawing:

Figure 1 is a view in front elevation of one of the units of the improved hinge;

Figure 2 is a like view of the improved hinge assembly; and

Figure 3 is a plan view of a form of link'used in connecting the units of the assembly.

Referring now to that embodiment of the invention illustrated in the drawing:l0 indicates the improved hinge assembly as a whole (see Figure 2) It comprises a plurality of identical units, each of the same length,-as a foot, a half foot, or other unit of length, multiples of which will meet a wide range of demand.

The hinge unit I I, shown in Figure 1, comprises the familiar flat, continuous leaves l2, l2, each provided with apertured or tubular knuckles l3 at their abutting edges, arranged in the familiar alternating end abutting relation found in hinges of the type. l4 indicates the hinge pin of the hinge unit ll. Said pin takes through the alternately disposed tubular knuckles of the two leaves I2 in the usual way to hinge the one leaf to the other. Said pin, however, terminates preferably about half way from the end of one end knuckle [3a of the hinge unit to leave an open socket l6 and has its other end l5 projecting a like distance beyond the other end of the hinge unit and/or said end knuckle I3b. The pin is anchored in one of the knuckles of the unit, as by a drive fit,

so as to retain the two leaves of the unit in hinged relation with the open socket IS in the end knuckle The hinge leaves [2 of the unit II are provided with projecting tenons I! at one end and with associated sockets H3 at the other end for connecting the leaves of the units together in assembled relation. To assemble the hinge, the alternate units may be swung on their hinge pin M to bring the leaves of successive units at different angles to each other, so as to clear the tenons; whereupon the projecting end [5 of the pin of each unit may be engaged in the socketv iii of the next adjacent unit. The leaves 12 of adjacent units may be then swung into the same plane to engage the tenons ll of one within the sockets l8 of the adjacent unit.

Preferably, links consisting of duplex tenon members I9 are punched from sheet metal of the same thickness as the hinge leaves l2. (See 20 Figure 3.) By the same or an identical tool or die, similarly formed duplex sockets l9a, I90. are punched in the leaves of the hinge units laid end to end. A duplex tenon I9 is then attached to each leaf by a drive fit of one part of the duplex 25 tenon into the socket at the end of the leaf. The other end of the tenon then projects, as heretofore described, for drive fit into the part of the socket in the corresponding leaf of the next adjoining unit.

As an alternative and possibly for readier connection of the leaves of abutting units when assembling the units, the duplex tenons l9 may be furnished separately. After the units have been assembled in abutting relation with the projecting 35 pins of one engaged in the socket of the next adjacent unit, the leaves may be folded into a. common plane and then with the assembly laid on a flat surface, the duplex tenons may be driven into the duplex sockets of abutting leaves.

I claim as my invention:-

1. A hinge assembly comprising a plurality of like units, each unit consisting of two leaves provided with apertured knuckles, a hinge pin taking through said knuckles and projecting beyond said unit at one end and terminating short of the other end of said unit to leave a socket, and means for locking abutting ends of the leaves of said units together when said units are in assembled relation with the hinge pin of each unit engaged in the socket of the next adjacent unit.

2. A hinge assembly comprising a plurality of units, each unit consisting of two leaves provided with apertured knuckles, a hinge pin taking through said knuckles and projecting beyond said 55 unit at one end and terminating short of the other end of said unit, leaving a socket in the end knuckle of the said unit of substantially the same length as the projecting end of the pin at the other end of the unit, and the leaves of the several units being provided with sockets at one end and with tenons projecting at the other end, the projecting pin and tenons of one unit being adapted for engagement Within the sockets of the next adjacent unit.

3. A hinge assembly, comprising a plurality of units, each unit consisting of leaves provided with alternately disposed apertured knuckles at their abutting edges, a hinge pin engaged in the apertures of said knuckles and projecting at one end beyond the unit and terminating short of the" other end to leave a socket at that end of the unit, the pin of each unit being engaged in the socket of an adjacent unit when said units are assem bled in abutting end relation, and tenon and socket means for locking the abutting ends of the leaves of said units together.

4. A hinge assembly, comprising a plurality of units, each unit consisting of leaves provided with alternately disposed apertured knuckles at their abutting edges, a hinge pin engaged in the apertures of said knuckles and projecting at one end beyond the unit and terminating short of the other end to leave a socket at that end of the unit, the pin of each unit being engaged in the socket of an adjacent unit when said units are assembled in abutting end relation, the leaves of the units being provided at their ends with sockets, and
